STARCH-PRESS.

SPECIFICATION formingpart of Letters Patent No. 227,537, dated May 11,1880.

, Application filed March 25, 1880. (ModeL) 'tion,arrangement, and combination of devices whereby a press is produced in which the process of extracting the water from the starch is accomplished entirely by mechanical means.

The accompanying drawings illustrate a mode of carrying out my invention.

Figure l is a side view, partly in section, of a press embodying my improvements. Fig. 2 is a transverse vertical section taken in the line 00 a: of Fig. 1. Fig. 3 is an end view. Figs. 4 and 5 are detail views.

Similar letters of reference indicate corresponding parts.

The working parts of the apparatus are supported by a base or platform, A, from which rise two standards, B B, on the top of which the press rests. The frame of the press is composed of a sill, G, and a top beam, D, connected by upright stanchions E. The sill O is providedwith two doors, G G, hinged to it on opposite sides. The hinges are provided with angle-arms, each hinge-joint carried by the door having two arms, 1) 10, at a right angle with each other, so that when the door is open it is supported in a horizontal position by said arms, as shown in Fig. 3. The door is provided on its inner side with transverse battens or cleats g g, for the purpose of strengthening it, and also to serve as Ways for thestarch-box to slide upon, as hereinafter described.

The starch-box H is of oblong form, and of such size as to enable it to fit nicely in the space above the sill O and between the stanchions E and doors G. The top of the box H is open, and its two sides and two ends are furnished with perforations h. One of its sides is removable, and is provided with bolts J, passing through dovetail joints i, for the purstarch-box, and provided with plungers l, corresponding in shape and size with the comlower are lugs m, which are internally threaded for engagement with the external threads of screws N. These screws pass through the top beam, D, and have heads a resting on said beam, and collars n bearing against the lower side thereof, by which means the screws are prevented from rising or falling, but are free to rotate. The lower endsof the screws carry bevel-wheels P, which mesh into wheels Q, carried by a horizontal shaft, R, journaled in the standards B B.

The shaft B may be rotated by any suitable means. It is here shown as driven by gearing S T, operated by a hand crank-shaft.

The operation of the apparatus above described is as follows: The starch is placed in the compartments of the box H, which is then placed on the sill G, and the doors G are closed and held closed by-latches V, which are vpivoted to the stanchions E. Motion being applied to the shaft R, the screws N are rotated, and by their engagement with the lugs m the follower K is caused to descend so that its 'plungers lwill enter the compartments of the ducted away. When the starch has been sufficiently compressed and has remained in the box a sufficient length of time, the motion of the shaft R is reversed, so as to cause the follower K to rise. The doors G are opened and let down to the horizontal position shown in Fig. 3, in which position they are held by the arms p, as before described. The box H is then withdrawn from the press and allowed to rest on either of the doors G, the cleats y allowing it to slide smoothly and easily. The bolts J are withdrawn, the removable side of the box is taken out, and the compressed starch is removed from the compartments in the shape of cubic blocks. The side of the box is repartments of said box. At the ends of said folplaced, the box is placed in the press, and the by the bolts J, passing through dovetail joints,

operation is repeated. in combination With a press, substantially as 10 Having thus described my invention, I and for the purpose herein described.
